There are deadly secrets at Bodiam Castle in East Sussex. We've put together a new audio adventure game to help us uncover some answers about the attempted murder of Sir Edward Dallingridge. Linda, part of our team here, has given the game a go. Read on to find out more:

'Looking for an escape from the computer screen, I collect my echo horn from castle cottage and, after a charming introduction by Jane, one of our Visitor Welcome Assistants, I'm off on my adventure around the castle to help Kate Dallingridge discover who might want to murder her father, Bodiam Castle's founder, Sir Edward.

A touch against the first seal and I am transported back to 1387 when the castle was newly built and playing host to many visitors, much as it still does today. The gentle urgency of Kate's voice propels me forwards to the second and third seals accompanied by the gentle strains of medieval backing music - a great way to inspire a lilting walk across the bridge and through the gateway into the courtyard beyond.

Now, it's decision time. Who shall I choose to follow - the powerful Richard FitzAlan, the Earl of Arundel, the devout but highly ambitious Prioress Katherine de Lisle, battle-hardened Sir John Hunt or the wily and daring Minstrel Pyk? I stop to consider my options before setting off in search of the seals that hold the echoes from the past to take me on an investigative trail around the courtyard, up the towers and into the remains of the rooms that were once an integral part of the grand home of Sir Edward Dallingridge and his family.

Snippets of conversation overheard gradually build a picture and slowly I am absorbed in the quest to help Kate find out who might have the desire to see Sir Edward dead.

I chose to start with one character and then switch to another to find our more information - there certainly seemed to be plenty of motivation. Time passes quickly and suddenly ...

Who is the culprit? Now that would be telling so you'll need to come along and find out for yourself. I'll be having another go and following a different route as I'm sure there is more to discover. Why not join me?'

Want to have a go yourself?

Look out for the signs around the castle grounds directing you to castle cottage where you can collect your echo horn, but don't delay, there are only 20 horns available and they're on a first come, first served basis.

You'll need about 30-45 minutes to help Kate, but there's no extra charge. Have a go as a family, on your own or with friends.

A first for the National Trust

This interactive audio investigation is a first of its kind within the National Trust. It was specifically designed for Bodiam Castle by Splash & Ripple, a Bristol based agency who describe themselves as architects of extraordinary adventures.
